9 Claims. (Cl. 28-54) This invention relatesv to warping machines, and relates more particularly to reeds for use on high speed section warping machines.

In high speed section warping machines, as

heretofore commonlyconstructed, the yarn bore against the dent wires and/or bar guides at one point cutting nicks therein, which nicks caused the splitting of threadswith a consequent impairment f the fabric'made from such threads.

Another factor which contributed to lower considerably the efiiciency of the prior reeds was that fly was caught in the reed wires'filling up the spaces therebetweenfcausingfurther yarn damage and unequal yarn tensions. p r j It is an object of this invention to provide an improved reed for warping machines which will be free from the above mentioned and other disadvantages and which will be'especially sim ple in construction and efficient in operation.v

Another object of this invention is the provi sion of a vertically reciprocating reed having bent or curved wires employed in conjunction with horizontally disposed guides so as to cause the yarn to wipe or polish both wires and guides instead of cutting the same. I

Other objects of'this invention, together with certain details of construction and combinations of parts, will appear from the following detailed description and drawings.

In the accompanying drawings?" 7 Fig. l is a front View, partly [broken away, of a warping machine creel showing the reed and guide of my invention applied thereto, Fig. 2 is an enlarged detail view'in perspective of one unit of reed and guide shown mm. 1,

Fig. 3'is a detail view of a. modification of the reed shown in Figs. 1 and 2 and shows the wires to be bent to anarc', "and Figs. 4 and 5 are detail views of other modifications of the reed.

Like; reference numerals indicate lik1e parts throughout the several views of the drawings.

While the reed and guide of my invention may be used in substantially all places where stationary reeds have heretofore been employed, for the sake of brevit and clarity it will be described in connection with the front reed on a high speed section warping machine.

Referring to the drawings, the reference numeral I generally indicates the frame of a warping machine broken away so that only one bank of reeds is shown. The frame as shown comprises an angle iron support I, a base 2 and a top cross-piece or head 3. Cross bars 4, on which the reeds are mounted, may be welded or otherwise attached to the support I and to any other braces, etc. (not shown) normally employed in such machines. On the base 2 is supported a speed reducer 5 on the input shaft 6 of which is fixed a pulley 1 driven from. a motor (not shown) or other suitable source of power by a belt 8. The output shaft 9 of the speed reducer. 5 carries a cam l I. A suitable bearing .12 and hand 'wheel [3 may be provided to support and manipulate, respectively, the output shaft 9. j

The pain! I. cooperates with a cam follower M which is journaled in the bifurcated lower end l5 of rod I6. The rod l6 passes through a series of guides I! attached to the cross bars 41 The rod It carries a plurality of arms 18 the length of which is governed by their position on the. machine. The arms may be attached to the rod 16 by welding, set screws or other suitable means. Where the arms I8 are of considerable length they may be braced by means of bars l9, one of which is shown bracing the bottom arm ill in Fig. 1'. Mounted on-the free ends of the arms [8- are rods 2| that operate inguides 22 attached to the cross bars 4. Each rod 2| supports a rack' 23. As the rod I6 is reciprocated by the rotation of cam' l'l, the'movement is imparted to the racks 23. A On the frame I and in alignment with each rack 23 is a block 24. The block 24 acts as a support fora plurality of horizontally disposed guide bars 25. On the machine shown in the drawing each block 24 supports a group of three -guide bars 2'5, but a greater or smaller number of guide bars may be employed. These guide bars 25. extend past but in relatively close proximity to a reed frame 26 mounted in a groove 21 formed in th rack 23. The reed frames 26 maybe of usual form. The reed'frame 26 is provided with wires or dents 28, each dent being bent out ofthe vertical to form an obtuse angle as shown in Figs. 1 and 2; to form an are as shown in Fig. 3; to form an open 8 as shown in Fig. 4; or bent through a number of smaller angles as shown in Fig. 5. Yarns 29 from a creel or other suitable supply (not shown) to be formed into a warp or the like are passed over the guide bars 25 and between the wires 28. There may be a yarn 29 over each guide bar 25 for each wire 28 as shown in Fig. 2, or a yarn may be passed over the top guide bar and between the first and second wires With the next adjacent yarn of the warp passed over the middle guide bar and between the second and third wires and so on, or any other method of threading the yarn through the guide bars and wires may be employed.

When the machine is in operation the reed frames 26 move up and down so that the yarn 29 moves along the wires '28 instead of bearing at one point and cutting them. With the reed frame 26 containing curved wires 28, angle wires, or multiple curve or angle wires, the yarn in the dent follows the wire and is moved back and forth laterallyon the guide abar :5' Thus; in-,- stead of" runninggiirone place on the bar, the yarn polishes a path on the bar commensurate in width to the curve or angle of the reed wire over which the yarn operates. Therefore, neither the wires or guide bars have nicks cut therein but both are wiped and polished by the yarn, keeping the same free of lint or fiyj- Both the life of the reed and guide bars are thus prolonged as the cutting of nicks in either is substantially avoided. Furthermore, the continually polished reed and bar, being free from nicks, efiectsa substantial reduction in the production of split threads, and consequently a better grade of fabric is obtained.

It is to be understood that the foregoing de tailed description is given merely by way of illustration and that many variations may be made therein without departin from the spirit of my invention.
